A 44-year-old man suspected of attacking his wife with the head of a hatchet, then killing his teenage nephews was taken into custody in Hong Kong, officials said Saturday.
Deyun Shi is wanted in connection with the attempted murder on Thursday of his wife at a home in La Canada Flintridge and the double murder of his nephews at an Arcadia townhome on Friday, sheriff's officials said in a news bulletin.
Shi was taken into custody and is "pending further review by officials in the U.S. and Hong Kong," according to Laura Eimiller of the FBI.
Two boys, ages 15 and 16, were found dead about noon on Friday by their mother and father, officials said. They suffered blunt force injuries.
The suspect's wife was hospitalized with serious wounds and released, said Lt. Eddie Hernandez, of the Los Angeles County Sheriff's Department.
The boys' uncle may have forced his way inside while the boys' parents were away tending to the suspect's wife at the hospital, Hernandez said.
FBI officials confirmed to detectives that he was on a plane to China.
The man became enraged upon finding out that his wife had filed for divorce and obtained a restraining order against him, officials said.
NBC legal analyst Royal Oaks said that America does not have an official extradition treaty with China, but there are unofficial ways to cooperate and occasionally the U.S. justice system does business with their justice system.
"This time an extradition might be in order since its nonpolitical and there could be informal behind the scenes strings pulled," he said.
